'nn'rronn'nrnn non RAILROAD RAILS.

Application filed August 23, 1922. Serial No. 583,808.

To all evhom it may concern: I

Be lt known that 1, Jesse. D. Gianna, a

citizen of the United States, residing at' VV atersville, in the countyof Carroll and State of Maryland, have invented certain new and usefulImprovements in Anticreep ers for Railroad Rails, of which the following1s a specification, reference being had to the accompanying"drawingsvide a device of this character capable of being applied to anyrailvwithout requiring alteration of the rail, or without rcqulringfastening means for connecting the device to the rail or he.

Another object of the invention is to provide a device of this characterincluding' jaw members adapted to engage a'rail,

and yieldably urged toward the rail in one direction, and means engagedwith the jaws -for urging the jaws in "the opposite directionintoengagement with the rail upon creeping movement of the rail. 25v

It is'a further object of the invention to provide a device of thischaracter including a pair of movably connected jaws, said jaws beingprovided with means for oscillating .the same'upon creeping movement ofthe rail. I U i With these and other objects in view, the inventionconsists in the improved construction and'arrangement of parts to behereinafter more particularly described, fully claimed andillustrated'in the accompany ingrdrawings, in which j igure 1 is a sideelevation of an anticreeper for railroad rails constructed-in ac- :therail; i

cordance with an embodiment of the invention, the anti-creeper beingapplied to The face 12 is' also inclined relative to This inventionrelates to anti-creepers for railroad rails, and has for. its object toproin the same plane. stops 13 and 18 limit pivotal movement ofbeyondthe side faces of the shank, said projecting portions having itsthe shank and disposed substantially parallel to the inner wall 11. Theopposite end portion of the enlargement, or that portion projecting fromthe opposite side of the shank, is canted as at 13 in the oppositedirection to the inclination of the face 12 and inner wall 11 of thesh'ankt'o provide a stop, said stop terminating substantially at thecentral portion of the shank. The end portion latof' the shank iscanted, the canted portion li being disposed in paral- 'lel' relation tothe canted portion 13 of" the stop. An opening 15 is provided in theshank 8 adjacent the canted end portion' 14. I

The jaw member 7 includes a shank 16 having an enlarged extension 17projecting from the end portion of one face of the shank, said enlargedportion havingits end face 18 canted to provide a stop similar to theend face 18, but cantedin the opposite direction to that of the cantedface of the stop 13. The extension 17 isalso reduced and undercut as at19 to form the jaw, the inner wall 20 of the jaw being canted withrespect to the shank and injthe opposite direction to the canted face181 The inner wall is serrated co-penetrate the rail.

The end face 21 of the jaw is likewise canted and disposed in parallelrelation to the end wall 20. j The end portion 22 ofthe shank is canted,said cantedportionbeing disposed in parallel relation to the cantedportion18. Said. end portion of the shank 18 is provided with an opening22*, the purpose'of which will be hereinafter described.

The shanks of the jaw members 6 and 7 are intended to be disposed oneupon the other, the under face of the shank 6 engaging the upper face ofthe shank 7. By the provision of the enlarged portions forming thestops, the outer faceof one jaw memher is permitted to lie flush withthe outer face of the adjacent jaw member, thereby positioning the jawmembers substantially At the same time, the

the jaws;

When the jaw members are assembled the "canted end face of one jawmember is disposed substantially parallel with the long1-.

'tudinal edge of the shank of the adjacent jaw member. Thus the jawmembers are disposed substantially in parallel relation to each otherregardless of the angular re lation between theshanks oi' the jaws s0 asto permit the jaw members to engage the rails at all pointslongitudinally oi? the aws.

In connection with the aws, an oper ating member 23 is provided, saidoperating member being longer than the shanks of the j aw members andhaving its end portion 2% beveled from the central portion to the end:tace oi the operatingamember so as to prevent projections at theconnection or the members to each other. The opposite end portion of theoperating member is provided with a :ioot 25 which extends in adirection opposite to that oi. the jaws and is intended openingsprovided in the shanks of the aw members 6 and 7. A pivot pin 27 ispassed through said openings to movably connect the operating member andjaw members to each other.

Each of the side faces of the shanks of the jaw members adjacent theoperating member is provided with an eye 28, to which one end of aspring 29 is connected. This spring is normallyintended to urge the awmembers substantially toward each other and into binding engagement withthe rail.

In operation, the jaw members are moved away from each other to permitthe insertion of rail A tl'ierebetween, the serrated inner walls 11 and20 oi the jaws engaging the edges of the rails. The jaw members are thenmoved along the rail until the foot 25 comes in contactwith one of therailwayties. Upon release of the jaws by the operator the spring 29willurge the jaws into binding engagement with the rail. It will be notedthat while the jaw members are disposed at anin clination to each otherand the operating-member, that in view of the inclination of theserrated inner walls 11 and 20, said walls are disposed parallel to theedgeof therail, so that yieldable movement of the spring will causebinding engagement of the aws on the ra-ils. Should the rail start tocreep, the movement of the rail will urgethe foot to firmly engage thetie, andcause pivotal movement of the shanks 8 and 18 relative to eachother. Thismovement permits the spring 29 to urge the aws into firmengagement with the edges of the rail.

During pivotal movement of the aw 1116111. iers .on the operating memberthe spring contracts, thereby urging the jaws into binding engagementwith the rail through the cooperation of the operating memberi23, as theoperating member is substantially urging the pivoted .ends of the shanksof the jaws away fron'i the spring, whichnaturally per- -i n1ts thespr1ng to pull the outer ends of the aw members inwardly so that adouble clamping operation is provided which causes without rigidlyattaching the device to the tie or the rail, other than the meansprovided by the serrated inner walls of the jaws, and all of t esefeatures are posse-ssedby a device which is composed of only threeparts.

These, in view of their simplicity and sub stantial qualities, willoperate under all'con ditions and will last indefinitely.

What is claimed is z 1. An anti-creeper "for railway rails comprisingjaw members movably connected to each 0ther,'means for normallyurging-the jaw members toward each other, and an actuating membermovably connected to the jaw members at the pivotal connection of saidjaw members to eachot-her.

2. An anti-creeper for railway rails comprising jaw members pivoted atone of their ends to each other, a spring connected at its ends to saidjaw members and normally urging the jaw members toward each other in onedirection, and an actuating lever pivoted to said jaw members at thepivotal connection of said jaw members to each other to permit thespring to urge the j awsinto binding engagement with the rail.

3. An anti-creeper for railway rails comprising a pair of jaw members,each jaw member including a shank, the end portions of said shanks beingdisposed one upon the ther, said end portions having registeringopenings, an actuating member having an opening in one end thereofadapted to register with said opening, a pivot pin connecting the shanksof the jaws to each other and to the actuating member, a foot carried bythe opposite end of the actuating member for engagement with, a railwaytie, said actuating member causing movement of the shanks of the jawsupon movement of the rail.

4. An anti-creeper for railway railscomprising a pair of jaw members,each jawiiiember including a shank, the outer trace of one end portionoi one shank and the mner face of one end portion of the remainlng shankbeing cutaway, said cut-away portion members being serrated, and cantedre-- spect to the shanks, an actuating member having one end thereofengaged with said ends of the shanks, a pivot pin extending through saidshanks and the actuating member, a spring connecting the shanks of thejaw members to each other andnormally urging the rail engaging faces of:the jaw members toward each other, said actuating member having a footon one end adapted to engage In testimony whereof I hereunto aflix mysignature.
